This example shows how to generate a shaded relief map using raster data, also known as a data grid.
This example shows how to determine the area satisfying one or more conditions using logical grid manipulations.
This example shows how to compute an elevation profile along a straight line using the
This example shows how to compute the gradient, slope, and aspect for a regular data grid.
A geolocated data grid is defined by three matrices giving latitude and longitude coordinates and indices associated with the mapped region.
Imagine an extremely coarse map of the world in which each cell represents 60º.
The latitude and longitude limits of a regular grid are among the most important properties of its referencing object.
You can access and manipulate gridded geodata using either geographic or intrinsic raster coordinates.
Before making a large, memory-taxing data grid, you should first determine what its size will be.
Raster geodata represents map data in matrix format.
Perform logic tests on data grid variables to create a binary logical grid.
Mapping Toolbox™ functions and GUIs display both regular and geolocated data grids originating in a variety of formats.
The dimensions of a map matrix and associated latitude and longitude matrices determines the interpretation of the geographic map data.
